### Single Double Stage Grinding Circuits

Closed circuit crushing is recommended for single stage grinding as there is greater control over size of feed going to the one ball mill. Open circuit crushing is advantageous when using two-stage grinding due to the ability of the rod mill to handle an over-size feed product.
